Statement-1 : A hollow cylinder of diameter `0.5 m` has a mass of `10 kg`. Its moment of inertia about its axis of symmetry is `0.625 kg m^(2)`.
Statement-2 : `I = MR^(2)`

Options

A. Statement-1 is true, Statement-2 is true ,
Statement-2 is correct explanation of Statement-1.
B. Statement-1 is true, Statement-2 is true but Statement-2 is not correct explanation of Statement-1.
C. Statement-1 is true, but statement-2 is false.
D. Statement-1 is false, but statement-2 is true.

Answer

A

Explanation

From `I = MR^(2) = 10 ((0.5)/(2))^(2)`
`= 0.625 kg m^(2)`
Both the statements are true and statement-2 is correct explanation of statement-1.
